Does anyone have the pinout for a simplex programming cable for the 4007es.
It appears to exist out there somehere but sadly no active users have the pinout on the below thread.
are you sure this pinout is accurate ? I am struggling to upload on a U
verified it is correct for the 4007es.
Take a look at this manual, 3-10
If everything is good, i would suggest verifying the cable continuity by moving it around. These cables go bad over time and might not keep good contact. Getting a spare one in case would be a good idea.
